The valve includes a valve seat (1) having passage channels (2) for the controlled medium which are arranged essentially in a ring-shape and concentrically, of a catcher (3) having flow-off channels (4), a valve plate (5) that is movably arranged, in particular it is movable back and forth, between the catcher (3) and the valve seat (1), having several individual ring plates (7) that are allocated to the passage channels of the valve seat (1), and a support plate (8) that is spring-loaded by the catcher (3) and rests on the ring plates (7). To allow for the guiding of each single ring plate (7) in the direction of lift with simple, joint springs, the support plate (8) includes individual, concentrically arranged support rings (9, 9') that overlap respectively two ring plates (7), which are guided on the guiding extensions (10) of the catcher (3) in the direction of lift, and the guiding extensions (10) are arranged on the radial cross-pieces (11) of the catcher (3), respectively in the areas of the outer and inner circumferences of the support rings (9, 9'), and protrude in the direction of the valve seat (1) to such an extent that the respectively adjacent ring plate (7) is also guided on it across the entire lift.
